prelude

The types required to implement a Widget.

Structs

Align	A widget that aligns its child.
Button	A button with a text label.
Checkbox	A checkbox that toggles a bool.
Click	A clickable Controller widget. Pass this and a child widget to a ControllerHost to make the child interactive. More conveniently, this is available as an on_click method via WidgetExt'.
ClipBox	A widget exposing a rectangular view into its child, which can be used as a building block for widgets that scroll their child.
Container	A widget that provides simple visual styling options to a child.
ControllerHost	A Widget that manages a child and a Controller.
DefaultScopePolicy	A default implementation of ScopePolicy that takes a function and a transfer.
Either	A widget that switches between two possible child views.
EnvScope	A widget that accepts a closure to update the environment for its child.
Flex	A container with either horizontal or vertical layout.
FlexParams	Optional parameters for an item in a Flex container (row or column).
IdentityWrapper	A wrapper that adds an identity to an otherwise anonymous widget.
Image	A widget that renders a bitmap Image.
Label	A label that displays static or dynamic text.
LensScopeTransfer	A ScopeTransfer that uses a Lens to synchronise between a large internal state and a small input.
LensWrap	A wrapper for its widget subtree to have access to a part of its parent's data.
List	A list widget for a variable-size collection of items.
Padding	A widget that just adds padding around its child.
Painter	A widget that only handles painting.
Parse	Converts a Widget<String> to a Widget<Option<T>>, mapping parse errors to None
ProgressBar	A progress bar, displaying a numeric progress value.
Radio	A single radio button
RadioGroup	A group of radio buttons
RawLabel	A widget that displays text data.
Scope	A widget that allows encapsulation of application state.
Scroll	A container that scrolls its contents.
SizedBox	A widget with predefined size.
Slider	A slider, allowing interactive update of a numeric value.
Spinner	An animated spinner widget for showing a loading state.
Split	A container containing two other widgets, splitting the area either horizontally or vertically.
Stepper	A stepper widget for step-wise increasing and decreasing a value.
Switch	A switch that toggles a bool.
TabInfo	Information about a tab that may be used by the TabPolicy to drive the visual presentation and behaviour of its label
Tabs	A tabs widget.
TabsState	This is the current state of the tabs widget as a whole. This expands the input data to include a policy that determines how tabs are derived, and the index of the currently selected tab
TextBox	A widget that allows user text input.
ValueTextBox	A TextBox that uses a Formatter to handle formatting and validation of its data.
ViewSwitcher	A widget that dynamically switches between two children.
Viewport	Represents the size and position of a rectangular "viewport" into a larger area.

Enums

Axis	An axis in visual space.
BackgroundBrush	Something that can be used as the background for a widget.
CrossAxisAlignment	The alignment of the widgets on the container's cross (or minor) axis.
FillStrat	Strategies for inscribing a rectangle inside another rectangle.
LabelText	The text for a Label.
LineBreaking	Options for handling lines that are too wide for the label.
MainAxisAlignment	Arrangement of children on the main axis.
TabsEdge	Determines where the tab bar should be placed relative to the cross axis
TabsTransition	Determines whether the tabs will have a transition animation when a new tab is selected.
TextBoxEvent	Events sent to a ValidationDelegate.

Traits

Controller	A trait for types that modify behaviour of a child widget.
ListIter	This iterator enables writing List widget for any Data.
ScopePolicy	A policy that controls how a Scope will interact with its surrounding application data. Specifically, how to create an initial State from the input, and how to synchronise the two using a ScopeTransfer.
ScopeTransfer	A ScopeTransfer knows how to synchronise input data with its counterpart within a Scope.
TabsPolicy	A policy that determines how a Tabs instance derives its tabs from its app data.
ValidationDelegate	A type that can be registered to receive callbacks as the state of a ValueTextBox changes.
